Toollibltomg't mag mm,; p Be it known that 'I, DAv1oRnYs Gmr' ririas, a subject of the King of the United Kingdom of Great Britain andlrela'nd, and 5 residing at Langside, Glasgow, Scotland,

have invented a certain new and useful 'Imrovement in Fastening M eans for Securing abric to a Base of Woodwork orOther Material, of which the following is a"specifica- This invention relates to fasteningmeans for securing fabric to a base of woodwork or other rigid material of the type in which the fabric is passed around a locking 16 strip which is inserted into a slot in the base and tilted in order to secure the fabric by its wedging action. The invention, is concerned more. particularly with fastenin means for securing fabric blinds to blin 20 rollers.

The object of the resent invention is to provide an improved construction of such fastening means which will be simple and cheap to manufacture, easy to manoeuvre and eflicient in action.

A feature of the invention is the provision of a spring or springs at the base of the slot nearer theunshouldered wall than the shouldered wall and adapted normally to ur e the strip towards the shoulder.

he invention is shown as applied to a blind roller in the accompanying drawing in which Fig. 1 is a section showing the locking strip in operative position and Fig.

2 a section showing the strip partly inserted in the slot.

As shown, the base constituted by a blind roller 1 to which the fabric 2 is to be secured is formed with an open-sided slot 3,

substantially rectangular in cross section, one wall of which is slightly hollowed out to form a shoulder 4:. Adapted for loose insertion in the slot is a locking strip 5 substantially square in cross section between which and the base the fabric is received. The fabric is laid over the open side of the slot 3 with its free or short end over the edge adjacent to the hollowed out wall and the main portion on the opposite side, the

locking strip being placed squarely thereon and pressed downwards as shown in Fig. 2. This downward movement is continued until the upper corner of the strip on the side adjacent to the hollowed out portion of the slot "can be pushed under the'shou-lder 4 by tilting thestrip as shown in Fig. 1. The fabric is thus gripped between the side walls 7 of the slot 3 and opposite corners of the tiltedlockihg strip 5. It will be obvious from 1 that any pullortensio'n applied to or'exerted by the main body of'the fabric will tend further to ,tiltthe locking strip and hence increase the gripping action. J g

"In order to assist the tilting action and to retain the locking strip in tilted position when no tension is exerted by the fabric itself, one or more springs 7 is or are fitted to the bottom of the slot near the plane side wall of the slot and are adapted to press upwards upon that corner of the locking strip which is diagonally opposite to the corner engaging the shoulder 4 as clearly illustrated in Fig. 1.

To facilitate tilting of the strip by the fingers or by a tool, when inserting it in place, the strip is preferably rebated as at 8.

I claim 1. Fastening means of the type specified, for securing fabric to a rigid base, comprising, in combination, a rigid base having an open-sided slot substantially rectangular in cross section with one side wall planeand the other side wall slightly hollowed out to form a shoulder near the open side of the 35 slot, and a locking strip substantially square in cross section adapted for loose insertion in said slot so as to permit said strip to tilt and wedge the fabric against said shoulder and the plane side wall of the slot, and re- 00 silient means to press against the under face of the strip.

2. Fastening means of the type specified for securing fabric to a rigid base compris ing, in combination, a rigid base having an 95 open-sided slot substantially rectangular in cross section with one side wall slightly hollowed out to form a shoulder near the open side of the slot, a locking strip substantially squar in cross section, and spring means 100 located about diagonally opposite said shoulder and adapted to tilt said strip beneath said shoulder.

3. Fastening means of the type, specified for securing fabric to a rigid base compris- 105 ing, in combination, a base having an opensided slot substantially rectangular in cross section with one side wall slightly hollowed out to form a shoulder near the open side of the slot, a locking strip substantially square in cross section provided with longitudinal grooves, and spring means located about diagonally opposite said shoulder and adapted to tilt said strip beneath said shoulder.

In combination, a base formed with an open sided slot substantially rectangular in cross section and formed in one wall with a V ioassi sure means serving to hold the strip in looking position in the slot.

5. In combination, a base formed with an open sided substantially rectangular slot, having one wall formed to provide a shoulder adjacent the open side of the slot a looking strip of substantially rectangular shape with a diagonal length greater than the transverse dimension of the slot, said strip being tiltable following its introduction into the slot to presentopposing diagonal edges to engage respectively beneath said shoulder and in contact with the opposite wall of the slot, and resilient means in'said slot to hold the strip in tilted position.

'In testimony whereof I have signed my name to this specification in the presence of two subscribin witnesses.
